Cellulose diacetate , sometimes called diacetate, is a synthetic polymer made by treating cellulose with acetic acid . It consists of two acetyl functional groups on each unit of D-anhydroglucopyranose of the cellulose molecule. It was first developed in the United States .

It is fragile since it is based on cellulose. When cellulose diacetate deteriorates, it shrinks and releases acetic acid causing vinegar syndrome .

Cellulose diacetate has been used to make fabrics, membranes, filaments, and many consumer products. From 1922 to 1957 it was used to make film stock , mainly in smaller formats such as 8 mm , 16 mm , 35 mm , and 70 mm . It has also been used in seed coating applications. ^[1]

In photography, a film substrate made from cellulose diacetate is called safety film.

Cellulose diacetate is hydrophilic ^[2] and biodegradable . ^[3]
